In electromagnetic waves or ocean waves, for that matter a crest is a peak or maximum height of the waveforms. The trough is the lowest point. The wavelength of a wave is evaluated from one crest (or peak) to the next or from one trough to the subsequent.
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
What does MeV in MeV photon signify? Briefly describe it.
Charles' law (J.A.C. Charles; c. 1787): The volume of an ideal gas at constant (steady) pressure is proportional to the thermodynamic temperature of that gas.
Super fluidity: The phenomenon by which, at adequately low temperatures, a fluid can flow with zero (0) viscosity. These causes are related with the superconductivity.
Illustrate the difference between the cathode ray and beta ray?
Huygens' construction: Huygens ‘Principle (C. Huygens): The mechanical propagation of the wave (specially, of light) is equal to supposing that every point on the wave front acts as a point source of the wave emission.
Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927): The experiment which conclusively proved the wave nature of electrons; diffraction patterns were examined by an electron beam penetrating into the nickel target.
